DEVICE FOR OPERATING WINDOWS OR SHUTTERS.

SPECIFICATION forming part of Letters Patent No. 740,953, dated October6, 1903- Application filed February 21, 1903. Serial No. 144,458. (Nomodel.)

Be itknown that I, EZEKIEL VAN Noonnnu, a citizen of the United States,residing at Boston, in the county of Suifolk and State of Massachusetts,have invented a new and useful Improvement in Devices for OperatingWindows or Shutters, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

My invention relates to an improved device for obtaining thesimultaneous closure or opening of a series of swinging sashes orshutters and for holding the same closed or at any variable degree ofopening.

My invention consists in certain details of construction theadaptability of which to the purpose for which they were designed canbest be seen and understood by reference to the drawings, wherein-Figure 1 shows my device in elevation as applied for operating twoadjacent sashes or where the sashes are arranged in series. Fig. 2 showsin elevation my device as applied for the operation of a single sash.Fig. 3 shows in cross vertical section the device applied to a windowwith the sash therein closed. Fig. 4 shows the same with the sash open.Fig. 5 shows a longitudinal cross-section of a certain detail of theconstruction, to which ref erence will hereinafter be made. Fig. 6 showsin cross-section a certain detail of construction, to which referencewill hereinafter be made.

Referring to the drawings, A represents a frame in which there arearranged a series of sashes A and between the jamb portions of which, asfrom an axial center a, the sashes are pivoted to swing horizontally.Extending inward from'the respective sashes and thereto above andbelowthe pivotal center of its support are the brackets B. These brackets aremade alike, and they are secured to the side rails of the respectivesashes to extend in uniform order, so as to be in line with one another,with which order of arrangement the brackets upon the adjoining siderails of the adjacent sashes are arranged in pairs, as may be seeninFig. 1. Each pair of brackets is united by means of a connecting plateor bar 11, preferably secured across their outer faces, and through themedium of which connecting-bar and brackets the adjacent sashes cansimultaneously be moved or swung.

Pivotally secured to the leaf of a hinge b, which hinge is attached toeach one of the cross-bars b, are the links 19 b YVith this method ofjointure the said links are capable of being spread apart longitudinallyfrom the center of their pivotal attachment to the hinge b or turnedhorizontally by reason of their connection therewith. The links b bdiverge, and at the lower ends they are pivotally secured .to the sidesof the longitudinal bars 19 19 respectively. These longitudinal bars 12b are subjected to considerable strain, as will hereinafter appear whenthe way in which they operate is'considered. Accordingly they are madeof angle-iron and are disposed alongside one another to have therelative order of arrangement shown in Fig. 6 or with the united barsforming a rectangular structure. By making the separate bars ofangle-iron they are made strong and rigid and are not easily twisted orbent. By arranging the bars as shown they reinforce one another. Thearrangement also facilitates the bars sliding by one anotherlongitudinally in reverse directions, which movement the bars have, aswill hereinafter appear. This formation and arrangement ofthelongitudinal bars, however, is a more detail of construction; but itis good by reason of its practicability. Y

Pivoted to the respective bars I) b are the links b b ,which links arepivoted,preferably,

by the same pivoted jointure as secures the I links 6 11 before referredto, whereby the links b b b b become practically pivotally joinedtogether in pairs. The links b 17 converge and at their lower ends arepivoted to the leaf of the hinge b which hinge is fixed to the frame,wherefore by such jointure the links b b may pivot longitudinally orturn horizontally, and for that matter the whole linked structure, ifsuch be necessary for its proper operation. Of course there may be asmany sets of links pivoted to the bars b b and pivotally hinged, asbefore explained, as is necessary, the number of course depending uponthe number of sashes or shutters to be operated.

. Pivoted to the ends of the respective bars 12 b are the links b 17"".These links converge and at their lower ends are pivoted to one leaf ofa hinge 12 which is secured to the frame, so that the links b b may turnhorizontally.

Pivotally secured to the sides of the links 12 b respectively, are thethreaded boxes or nuts 12 b through which extends longitudinally theright-and-left screw 1). The screw o by reason of its variable combinedhorizontal and vertical movement is guided by a cam-surface 17 of abracket Z7 which is.

secured to the frame. By reason'of its variable motion also the screw 12is turned by the universal-coupling connection Z2 which connects,through suitable bearings, with a pulley Z7 or any other suitable meansof turning.

The operation of the various parts referred to is as follows: Assumingthe sash to be closed, the parts have the relative order of arrangementshown in Figs. 1 and 3. Upon turning the right-and-left screw 17 thelinks b N, carried by the traveling nuts, are rapidly run apart. Thismot-ion of the links is imparted to the bars 19 b and they in turn aremoved in a longitudinal direction reverse to one another, carrying withthem the links 1) 17 which have pivotal attachment with these respectivebars, as before explained. The truss structure formed by the links isaccordingly longitudinally extended at both sides, and consequently itsvertical extension is relatively shortened; but the lower end of thelinked structure, by reason of the links 6 b being fixed with the framethrough their hinged connection I), is incapable of a vertical movement.The objective result is therefore necessarily obtained that the sashesmust be turned by the downward draft of the linked structure upon thebrackets B, to which the structure is secured by the ends of the linksI) b and through the medium of the hinges b and connecting cross-bars b.As the sashes pivot, of course the brackets B, fixed to them, are causedto move longitudinally to describe an are, so that the truss structure,like as I have described, which is connected with these fixed brackets,or rather to their connectingbars I), must likewise have some degree ofhorizontal turning, which is attainable by the hingedjointure of thelinks 19 b and links b b to the said cross-bars and the frame,respectively, and it is to be observed in this connection that the trussstructure, comprising the longitudinal bars and links through the pointwhere it makes its hinged jointure with the frame, has a most variablemovement in its operation, consisting of a longitudinal movementincident to the primary movement of the longitudinal bars and thesimultaneous vertical and horizontal movement consequent upon theturning of the sashes, all of which movements are attainable by themethods of jointure before described. The right-andleft screw b, bywhich the reverse movement of the longitudinal bars is obtained, remainsduring its operation in relatively one position against a longitudinalmovement; but ithas a vertical movement following upon the divergence ofthe links 11 b Of course the relative position of the screw b and thelinks 19 17 becomes changed by their divergence, and this is providedfor by the traveling nuts, which compensate for such relative change ofposition and provide a free running of the screw whatever the positionof the links may be. The screw, together with the links, turns alsohorizontally with the main structure before referred to, which movementis permissible by the hinged jointure of the saidlinkstotheframe.Thescrewb isguided in its combined vertical and horizontal movement bythe cam-surface Z1 of the bracket 5 as before explained. Theadaptability of the universal coupling to the variable motion of thescrew is apparent.

In Fig. 2 a change of feature is shown in the fact that instead ofsimultaneously operating adjacent sashes the device is applied for theoperation of individual sashes. There is no essential variation in theconstruction, onlyinstead of attaching the linked structure to thecross-bars connecting the brackets extending from the adjacent sashesthey are directly secured to the brackets themselves, which are securedto the sash sides, as before explained. In point of fact,it makes nodifference respecting the essence of my invention how many bracketsthere are or how they may be arranged, provided that all the sashes maybe simultaneously closed by a means substantially like as I havedevised; but the method referred to by which adjacent sashes can besimultaneously closed is perhaps the most practicable, especially ifthere are a series of windows.

My device is very simple. It is made up of parts which can be easilyobtained and which do not require a special construction. It can easilybe applied to any windows without changing their structure in any way.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.Adeviceforoperatingoneormoreswing ing sashes or shutters, the samecomprisinga bracket fixed to and extending from each sash or shutter, alongitudinally-extending bar below said brackets longitudinally movable,a link connection between said bar and brackets, the same being pivotedto said bar and having a hinged and pivotal jointure with said brackets,and a link connection below said bar, the same being pivoted to said barand making a hinged and pivotal jointure with a fixed base of support,substantially as described.
